2. Click the Exhibit button.
A customer has a DL4200 connected to two switches in the same fabric, as shown in the exhibit. Windows Backup Server X is zoned to port 1 on Engine A and Windows Backup Server Y is zoned to port 7 on Engine B. Active Engine Failover has been configured and is active.
Both backup servers are performing backups at the same time to their respective engines. Engine A has a failure and all virtual services fail over to Engine B.
The backup administrator has verified that failover has occurred as expected but Backup X is unable to see its virtual resources through the surviving engine even after rescanning the SCSI bus.
